Application filed March 30, 1922, Serial No. 548,000. Renewed September19, 1928 This invention relates to soot cleaners for locomotives of thattype which comprises a nozzle or jet pipe which is normally received.

in a pocket formed in the water leg of the boiler at the side of thefire-box but which may be projected from the pocket into the fireboxwhile steam isdelivered therefrom into and through the fiues forcleaning them. One of the objects of the invention is to provide animproved soot cleaner of this type in which the means for projecting thenozzle orjet' pipe from the pocket into the fire-box and also the meansfor turning the jet pipe on its axis, are located in close'proximity toeach other so that they can be easily manipulated.

Another object of the invention is to provide a soot cleaner havingnovel means for turning the nozzle on its axisby which the movement ofthe nozzle can be accurately controlled, thus making it possible tothoroughly clean all of the flues.

Other objects of my invention are to improve generally soot cleanersofthis type all as will be more fully hereinafter set forth;

In order to given an understanding of the invention I have illustratedin the drawings a selected embodiment thereof which will now bedescribed after which the novel features will be pointed out in theappended claims.

Fig. 1 is a fragmentary Sectional view through a portion of a locomotiveboiler showing my improved soot cleaner applied thereto. 7

Fig. 2 is an enlarged section on substantial-. ly the line 22, Fig. 1.

Fig. 3 is a section on the line 33, Fig. 4.

Fig. 4 is a view of the soot cleaner looking toward the right in Fig. 2with a part broken out to better show the construction.

Fig. 5 is a sectional view of one of the swivel j olnts.

In Fig. 1 of the drawings I have shown in horizontal section asuflicient portion of the fire-box to enable my invention to beunderstood and in said figure, 1 indicates the barrel of the locomotiveboiler which is provided with the combustion chamber 2 therein forwardlyof which is the usual flue sheet 3 carrying one end of the fiues 4 thatlead into thefire-box. At the side ofthe fire-box. is the usual waterleg 5 formed between the inner and outer sheets 6 and 7 and this waterleg extends around to the front of the fire-box.

tion chamber is indicated at 8, and 90indi- 1 and in full lines Fig. 3when for cleaning the flues, and my invention re cates in section thewall of the cab. It will be understood that Fig. 1 is intended toindicate a horizontal section through the firebox of the boiler. 2

My improved soot cleaner is of the familiar. type which embodies a jetnozzle 9 having a jet opening 10 therein through which steam is adaptedto be delivered against the flue sheet 3 for blowing out the flues. Thisjet nozzle is normally confined withinv a pocket 11 formed in the waterleg 5, said pocket being hereln shown as constituted by a tube 12extending across the space between the sheets.

6 and 7. This jet. nozzle 9 is arranged to be withdrawn intofthe pocketas shown in dotted lines Fig. 3 when it' is not in use, and to be proected into the fire-box as shown in Fig. it is to be used lates to novelmeans for manipulating the nozzle to project it into the fire-box andthen to turn it about its axis so that the steam issuing therefrom willbe directed toward any horizontal row of flues.

Secured to the outside sheet '7 is a fitting or casing 13 havinga steampassage 14 leadng to a chamber 15. A steam pipe 16 leads mto the passage14, said steam pipe communieating with a steam boiler or other suitablesource of supply.

The nozzle 9 has a hollow stem or pipe17 extending into the chamber 15and provided with ports 18 which communicate with the chamber when thenozzle is projected. The chamber 15 hasan extension 19' at its rear endinto which the ported end of the stem 17 is received when the nozzle isretracted, and this chamber is of a sizeto fit the stern so that whenthe nozzle is retracted, as shown in dotted lines the ports are closedby the walls of the chamber extension 19 thus shutting off steam fromthe nozzle. The stem is formed with the shoulder 22 which seats againstthe inner wall 23 of the chamber extension 19 when the nozzle isretracted thereby assisting in preventing leakage of steam past thestem. 7 The stem or pipe 17 is extendedor rothe fire-box and also forturning the stem are connected to the end of the stem extension 20.

The fitting 13 is shown as having a rock shaft 24 journalled thereinwhich is pro- "side the boiler and is )lfOYl Le titled with two armssituated at either side of the fittiiii liese a1 ns have 11 ks 26pivotally connected" tbereto at'27, said; links in turn being pivoted toa collaror yoke 28 Which is swiyelled Q11 the lend of the stem extension20.
